local image through local json in android

Let's imagine that you have some images in your drawable folder:

drawable    image_name_1    image_name_2    image_name_3    image_name_4    ...

Put the name of image to json:

[    {        "some_field_1": "some_value_1",        "some_field_2": "some_value_2",        "some_field_3": "some_value_3",        ...        "image_name": "image_name_1"    },    {        "some_field_1": "some_value_1",        "some_field_2": "some_value_2",        "some_field_3": "some_value_3",        ...        "image_name": "image_name_2"    },    {        "some_field_1": "some_value_1",        "some_field_2": "some_value_2",        "some_field_3": "some_value_3",        ...        "image_name": "image_name_3"    },    ...]

Get name from JSON and load drawab resource:

    JSONArray data; // your JSON    Context context; // context    Resources resources = context.getResources();    for (int i = 0; i < data.length(); i++) {        // getting some another JSON field        // get image name from JSON        String imageName = data.getJSONObject(i).getString("image_name");        // get resource id by image name        final int resourceId = resources.getIdentifier(imageName, "drawable", context.getPackageName());        // get drawable by resource id        Drawable drawable = resources.getDrawable(resourceId);        // get bitmap by resource id        Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), resourceId);    }

Update

Put image resource id into HashMap

    ...    List<HashMap<String,String>> aList = new ArrayList<HashMap<String,String>>();    JSONArray data; // your JSON    Context context; // context    Resources resources = context.getResources();    for (int i = 0; i < data.length(); i++) {        HashMap<String, String> hm = new HashMap<String,String>();        hm.put("txt", "Country : " + countries[i]);        hm.put("cur","Currency : " + currency[i]);        // get image name from JSON        String imageName = data.getJSONObject(i).getString("image_name");        // get resource id by image name        final int resourceId = resources.getIdentifier(imageName, "drawable", context.getPackageName());        hm.put("flag", Integer.toString(resourceId) );        aList.add(hm);    }

//if you have a model class then this code help you

 try {        JSONObject jsonObject = new JSONObject(loadJSONFromAsset());        JSONArray array = jsonObject.getJSONArray("Details");        Resources resources = this.getResources();        for (int i=0;i<array.length();i++){            // Parse the JSON            JSONObject jo_inside = array.getJSONObject(i);            String title = jo_inside.getString("title");            String img = jo_inside.getString("img");            // get resource id by image name            final int resourceId = resources.getIdentifier(img, "drawable", this.getPackageName());            //load Model Class            Model_Home data = new Model_Home(title,resourceId);            indexList.add(data);        }    }catch (JSONException e){        e.printStackTrace();    }

enter  try {    JSONObject jsonObject = new JSONObject(loadJSONFromAsset());    JSONArray array = jsonObject.getJSONArray("Details");    Resources resources = this.getResources();    for (int i=0;i<array.length();i++){        // Parse the JSON        JSONObject jo_inside = array.getJSONObject(i);        String title = jo_inside.getString("title");        String img = jo_inside.getString("img");        // get resource id by image name        final int resourceId = resources.getIdentifier(img, "drawable", this.getPackageName());        //load Model Class        Model_Home data = new Model_Home(title,resourceId);        indexList.add(data);    }}catch (JSONException e){    e.printStackTrace();}
